Anti-icing Skin with Micro-nano Structure Inspired by Fargesia Qinlingensis
摘要
Abstract
Aircraft icing has a significant impact on flight safety,as ice accumulation on airfoils and engines can cause aircraft stalls.Developing anti-icing technology that can adapt to harsh and cold environment presents a challenge.Here,we propose a new anti-icing skin with micro-nano structure inspired by the bamboo leaf called Fargesia qinlingensis.A multilayer non-uniform height(MNH)micro-nano structure is proposed based on the Fargesia qinlingensis surface structure.The anti-icing mechanism of the MNH micro-nano structure is revealed.The flexible large-area MNH micro-nano structure is fabricated based on hierarchical assembly method.Compared with the smooth surface,the ice adhesion strength of the prepared bio-inspired surface is reduced by 80％,indicating that the MNH micro-nano structure inspired by Fargesia qinlingensis has ice-phobic effect.Based on this,an anti-icing hybrid skin based on bionics and electric heating is developed.The anti-icing hybrid skin has successfully completed the anti-icing function flight test on the UAV.To realize the effective anti-icing function under super cold conditions,the anti-icing hybrid skin has been applied on a certain type of UAVs.The bio-inspired anti-icing skin has broad application prospects in large transport aircraft,helicopters,wind power generation,and high-speed trains.关键词
